New Honda-powered Red Bull RB15 F1 car unveiled at Silverstone

Red Bull unveiled their first Honda-powered Formula One car on Wednesday with Max Verstappen driving the initial laps at Silverstone.

The team published images of the RB15 online with what it said was a temporary livery for filming before testing starts in Spain on Monday.

The former champions finished third overall last season, winning four races and well ahead of fourth-placed rivals Renault.

Red Bull parted company with engine partners Renault at the end of 2018, switching instead to Honda who also provide power units for sister team Toro Rosso.

Verstappen, who shared the victories with Australian Daniel Ricciardo last season, has a new team mate for 2019 in Frenchman Pierre Gasly.

"What I'm most looking forward to is starting the season and seeing how the whole team is operating together with Honda and how the engine is performing together with the chassis," said Verstappen ahead of the initial limited mileage filming day.
